To all whom it may concern:

Be it known that I, GEORGE E. HITCI-ICOCK,

a citizen of the United States, residing at Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Stoppers for Non- Refillable Bottles, of which the following is a specification.

My invention relates to an improvement in bottle stoppers, and it comprises four elements, to wit, a ferrule which has a slight external taper to enter the neck of the bottle, and the bore of which is of two diameters, the shoulder between the two being milled to form a valve-seat; a valve, the inner portion of which loosely fits the smaller bore of the ferrule, and the head of which fits the valve-seat; and a tap with a milled head and a hollow barrel, which latter has a valve-seat at one end between which and the head of the valve a ball is held, and provided with oppositely-located spiral orifices to receive a pin which goes through the ferrule, which causes the tap to move in and out as turned to the right or left, and having slots adjacent to the milled head which are exposed when the tap is screwed, and through which the liquid discharges in pouring the contents out of the bottle.

In the accompanying drawings: Figures 1 and 2 are Views in elevation with parts broken away showing the position of the parts when the milled tap is in its two extreme positions; Fig. 3 is a vertical section; and Figs. 4 and 5 are views in side elevation taken at right-angles to each other of the milled tap.

The numeral 1 represents the ferrule. This preferably tapers slightly from one end to another, and its center is bored on two diiferent diameters, and the shoulder between the two diameters is beveled to form a valve-seat 2.

The numeral 3 represents the valve, which has a head 4 fashioned to fit the valve-seat, and a sleeve 5 which loosely enters the smaller bore of the ferrule, and when the valve is seated preferably extends somewhat beyond the inner end of the ferrule. This sleeve is perforated to permit the contents of the bottle entering the inner or open end of the sleeve to escape when the valve is unseated.

A tap comprising a milled head 6 and a hollow sleeve 7 is notched as at 8 at its outer edge, and milled to form a ball-weightseat 9, and a ball-weight 10 is interposed between this seat and the head 4 of the valve 3, and substantially fill the space therebetw'een when the tap is turned or screwed inward. The barrel 7 of the tap is further provided with oppositely-located and inclined spiral slots or guides 11, 11, which receive the pin 12 which extends diametrically through both of these slots and through the oppositely-located holes 13, 13, in the ferrule. Discharge openings 14, 14, are formed in the ferrule preferably opposite each other and just adjacent to the. head 6 of the tap, through which the fluid escapes when pouring from the bottle.

The spiral slots act like a screw-thread, and when the tap is turned to the right, it moves inwardly and closes the valve 3 by pressing the ball against the head 4 thereof, and, when thus turned, not only is the valve seated but the outlets 14, 14, of the tap are inside of the ferrule and consequently closed. When it is desired to pour out the contents of the bottle, the tap is turned in the opposite direction as far as it will turn, which is about one-fourth the way around. This opens the outlets 14, 14, and by lengthening the space within between the valve-head 4 and the ball-weight-seat 9, it permits the valve to be unseated by the pressure of the fluid from within, which flows through upon the inner end of the valve-sleeve, thence out through the holes therein beneath the valvehead, and then through the barrel of the tap, and out through the outlets 14, 14. In this way, a simple stopper is formed which will make a bottle non-refillable. The parts are not only few, but of such a type and character that they are easily made and assembled, and when the stopper is once cemented or otherwise fastened in the bottle neck, the pin 12 cannot be withdrawn as it is held in place by the bottle-neck.

I claim:

1. A stopper for non-refillable bottles comprising a ferrule adapted to fit abottle neck and having a valve seat at the inner end, a tap having a knurled outer end adapted to close the outer end of the ferrule and having a spirally slotted sleeve with a notched seat at the inner end, a ball, and a pin extending through the spiral slots into the wall of the ferrule for holding the tap in the ferrule, for limiting the extent of its turns to right or left and for causing it to move in or out as it is turned.

2. A stopper for non-refillable bottles comprising a ferruleadapted to lit the bottle neck and having a valve-seat formed therein, a valve fitted to the seat, a ball Weight, a tap comprising a milled head adapted to fit and close the outer end of the ferrule and said tap ,fitted to the inside of the ferrule and having spiral slots or guides and discharge openings, a pin extending through the spiral slots or guides and into holes in the ferrule, the tap notched at the inner end and milled to form a ball Weight seat whereby to hold the ball upon the valve to keep the latter closed When the tap is turned in one direction and releasing 1.5
